What is the trim of SSD solid state drive?
The trim of SSD can avoid the use of useless data as useful data in the garbage collection, so as to prolong the life of SSD. In HDD mechanical hard drives, the logical location of the deleted files is marked so that the data can be stored directly in the logical position of the unwanted data at a later time. However, SSD solid-state drives do not have this mechanism, and the master does not know that the data is useless until new data requirements are written to the block. This will result in useless data being treated as useful data in the garbage collection (GC) process, which will undoubtedly greatly reduce hard disk efficiency and service life. So the appearance of trim can make up for the defect of the problem.
